Radiation Measurement Using Optical Techniques.

Optical Radiation Measurement

Speed Measurement by Optical Techniques

The most obvious optical method for measuring the speed of a moving object is to use the Doppler effect: light reflected from the moving object will be shifted in frequency on proportion to the line of sight velocity of the object. While we are familiar with examples in the radio domain (such as police traffic radar and Doppler weather radar) and with acoustic waves (the apparent change in pitc...

Beam Profile Measurement at 30 GeV Using Optical Transition Radiation

We present results of measurements of spot size and angular divergence of a 30 GeV electron beam though use of optical transition radiation (OTR). The OTR near field pattern and far field distribution are measured as a function of beam spot size and divergence at wavelengths of 441, 532, and 800 nm, for both the single and double foil configurations. Electron beam spot sizes of 50μm rms have be...

Optical measurement techniques with telecentric lenses

This course on optical 2d-measurement technique has been created during the development of the telecentric lenses from Schneider-Kreuznach. First of all we had the idea to explain to the "non optics expert" the differencies between normal lenses and telecentric optical systems by introducing the laws of perspective (Chapter 2). But in the course of writing it became very soon evident that we ha...

Infant Head Circumference Measurement Using Deep Learning Techniques

Infant's head circumference measurement and and its growth monitoring plays a crucial role in diagnosis the diseases which cause a deformation in the infant's head. Due to the fact that the contact measurement, which is performed using a tape measure and a caliper, has problems such as transmitting disease, infecting, not comfortable and disruption relaxing the baby, going to non-contact measur...
